Local Environmental Conditions
Around the center of Biggar, a mix of built-up land and open space means traffic is an important, but not overwhelming, local pollution source. Traffic on Highway 14 adds to local emissions. Home heating, especially wood stoves and fireplaces, adds smoke and fine particles in the colder months. Levels are generally highest right next to busy roads and drop off quickly with distance.
The cooler months, October to April, see more fine particles, as home heating and traffic add emissions while frequent calm, cold mornings around -12°C keep pollution near the ground. In the warmer months, summer sun in July cooks traffic fumes into ozone, especially in the warmest month, which averages 20°C. Plowing and harvest in the nearby fields bring occasional spikes in dust.

Frequently Asked Questions About Air Quality in Saskatchewan
Is air quality bad in Biggar right now?
On 10 October 2026, overall air quality in Biggar is fair. AQI is the main air quality indicator at 33.4/100. Pollution peaks around 2:00 PM (NO2: 33.4/100).

When is air pollution at its worst in Biggar?
The cooler months, October to April, see more fine particles, as home heating and traffic add emissions while frequent calm, cold mornings around -12°C keep pollution near the ground. In the warmer months, summer sun in July cooks traffic fumes into ozone, especially in the warmest month, which averages 20°C. Plowing and harvest in the nearby fields bring occasional spikes in dust.
Are air quality levels in Biggar based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
Understanding the Scale
The 0–100 air quality scores represent risk levels, not direct air pollutant concentrations. Higher scores indicate higher risk.
Air Quality
| Good | 0-20 | Low air quality risk. Air quality is expected to be good, with low levels of pollution. |
| Fair | 20-40 | Generally low air quality risk. Air quality is expected to be acceptable, with some pollution present. |
| Moderate | 40-60 | Moderate air quality risk. Air pollution is elevated and air quality may be less favorable. |
| Poor | 60-80 | High air quality risk. Air pollution is high and air quality is expected to be poor. |
| Very Poor | 80-100 | Very high air quality risk. Air pollution is very high and air quality is expected to be very poor. |
